Cos no-one listens to RTL
Quite honestly dont know,haven`t been in Germany for a good long while,however when I was there last (late 80s)we spent most of the time in the field,one squadron or another,and we didnt have fax machines or computers in the CPs but we always had a radio(ghetto blaster not clansmen,although we did have them as well!)so it was a handy way to get Met daily.
Dont know if this was the sole reason,maybe someone else can shed more light.
